NOAA’s Role in Improving the Use of Satellite Information
• User Engagement - listening, learning and understanding user needs
• Satellite missions – providing long-term continuity of key observables.
• Free, Open and Easy Access to the NOAA suite of products and services
• Use Inspired Science
• Use-inspired science consists of scientific investigation whose rationale, conceptualization, and research directions are driven by the potential use to which the knowledge will be put (Stokes, 1997).
• Satellite Proving Grounds - engaging the user community to promote and improve the use of satellite observations and products for user applications and services.
• Training - providing educational and training material to the user community
• Stewardship – establish authoritative quality, uncertainties and provenance

Science across the NESDIS Enterprise and Lifecycle
• Preformulation Science Studies. -- Weather Research and Innovation Forecasting Act of 2017: OSSEs must be conducted before: (1) acquisition of major government-owned or government-leased operational observing systems with a lifecycle cost of more than $500 million, and (2) purchase of any major new commercially provided data with a lifecycle cost of more than $500 million.
• Instrument science related to prelaunch and post launch activities
• Scientific algorithms to derive products from satellite observations
• Application of satellite observations and products to support understanding and decisions
• Services, Assessments, and Stewardship

Instrument Science (ATMS)
• Science activities include intensive instrument prelaunch characterization and post
launch assessments.
SNPP ATMS analysis revealed that the receiver front-ends had noise issues which resulted in striping and correlated noise. This problem was fixed in JPSS-1 (NOAA-20) and prelaunch testing of ATMS for JPSS-2 shows further refinement significantly reduced correlated error.

Enterprise Proving Ground has 3 main objectives
• Assessing “Fit for Purpose.” Fine tuning
products for new project applications
• Are the products “Fit for Purpose”; are they
meeting expected utilization?
• Are there opportunities for unrealized “Fit
for Purpose”?
• Product Innovation. RL 2- 5
• Can NOAA services be improved by new
products and/or enhancing current ones?
• Product Innovation Demonstrations. RL 6
• Full demonstrations of promising product
innovations to get complete feedback from
users before commitment to operational
development and deployment.
